# Dockerfile for mcp-server-excel
# ============================================================================
# PURPOSE: Glama.ai Tool Discovery and MCP Registry Inspection ONLY
# ============================================================================
#
# This Dockerfile exists solely to enable Glama.ai (https://glama.ai) to:
# - Inspect the MCP server and discover available tools
# - Display tool schemas, parameters, and descriptions in their registry
# - Allow users to browse capabilities before installing locally
#
# IMPORTANT LIMITATIONS:
# - This container CANNOT perform actual Excel operations
# - Excel COM automation requires Windows + Microsoft Excel installed
# - For real Excel automation, install the MCP server locally on Windows
#
# See: https://glama.ai/mcp/servers/@sbroenne/mcp-server-excel
